Important notice about ASL360-SVS
The ASL360 Surround View system provides on a display, a simulated plan view of the vehicle
surroundings, as if a camera were mounted high overhead above the vehicle. However, this
view is formed by cameras mounted on the vehicle and not overhead in the air. As such, the
composite view is not a true overhead plan view and objects will appear distorted due to the
physical locations of the cameras. Moreover, in regions where the views from adjacent
cameras are combined, objects (pedestrians, vehicles etc.) may appear distorted, or partial,
since the image comes from two cameras pointing in different directions. Due to the nature of
the system, objects may not appear exactly as their real location with respect to the vehicle;
objects may be physically closer than they appear. In particular, objects above the ground, or
objects on ground higher than the ground on which the vehicle is operating, may be closer
than they appear and could be out of view.
It is imperative that ASL360-SVS is fitted and commissioned by competent and trained
technicians. The installer is responsible for the fitness for purpose of the overall
system and adherence to regulations and legislation. Operators of the vehicle to which
ASL360-SVS is fitted must be fully trained and have been made fully aware of how to
interpret the images provided by the system and will not be distracted by or rely on it.
Distraction can cause accidents.
The system is intended to aid the operator, who must still concentrate on operating the
vehicle, obey traffic and local regulations and continue to use his/her own training, senses and
other vehicle aids, such as mirrors, as would be done if the system were not in place. Nothing
removes the responsibility of the operator to operate the vehicle in a proper and lawful
manner.
Notice: Application Solutions (Electronics and Vision) Ltd accepts no responsibility for
consequences of misuse of the system or non-compliance with the above guidelines.

1. Introduction
The ASL360 Surround View system has great potential to significantly improve road and off-
road safety and to reduce fatality statistics, especially of vulnerable users by helping to
eradicate blind spots around the vehicle.
Blind spots are areas around a vehicle that are obscured from the operator’s direct or indirect
view by the vehicle’s bodywork and/or machinery. Blind spots present significant danger to
other people or objects close to the vehicle and limit the users’ ability to operate and
manoeuvre the vehicle or its machinery safely and effectively.
ASL360 is a multi-camera, video DSP-based system designed to provide a view all around the
vehicle by combining video from a suite of cameras mounted on the vehicle periphery.
The ASL360 system may be used in automotive environments including, but not limited to:
passenger vehicles, buses and public transport, heavy goods vehicles, agricultural vehicles,
earth-moving equipment and mining vehicles.
1.1 About this document
Much of the information in this document is of interest to the installer.
There is one section (18) which is directly relevant to the person who drives the vehicle to
which ASL360 has been fitted. The installer should ensure that the driver fully understands the
content of this section. For large operations it may be appropriate to delegate this duty to the
fleet/site operator.

1.3 Configuration Tool screen shots used in this document
To help explain how to use the ASL Configuration Tool this document shows screen shots
taken from Configuration Tool. The version used was v2.4 running under Windows XP. Users
may observe minor differences between these screen shots and the appearance of later
versions of the Configuration Tool.
The Windows 7 user has the option to select different desktop themes. The appearance of the
Configuration Tool running on Windows 7 will most closely resemble the screen shots in this
document if the “Windows Classic” theme is selected.

4. Description of system functionality
The system provides the driver/operator with a real-time, synthesized bird’s-eye image of the
vehicle using multiple wide-angle cameras typically mounted on the front, sides and rear of the
vehicle.
The system is also capable of presenting different views to the driver. If it is desirable that
these views are shown automatically without driver initiation, this can be achieved by
connecting the ECU’s inputs to suitable vehicle signals, e.g.: reverse gear engaged, speed
threshold signal etc. It will be necessary to configure the ECU to respond to these signals in
the desired manner – refer to [2].

Camera power is provided by the ECU, and is a conditioned feed derived from the power fed
to the ECU.
Video signalling is differential and should provide a high degree of immunity in situations
where the ECU and cameras are exposed to differential ground noise.
The camera control line provides a means to update the camera firmware, and allows the
ECU to control the camera’s imager settings.
Normally the camera is connected to the ECU with supplied extension cables. Should the
installer choose to make alternative connections, the camera’s flying lead cable is described in
section 22.2.

> 10 V after low-voltage shutdown
Starts operating (reboots)
> 33 V non-transient

< 31 V after over-voltage shutdown
ECU reconnects and restarts (reboots)
Table 5 - Response of ECU to power supply –voltages
The ECU is load dump tolerant in 12 V and 24 V systems as defined by 2004/104/EC.
5.2.2.2.2 Input protection
All inputs (including video inputs) are protected against single fault short-circuits to +32 V or 0
V, with the exception of:
VGA video output
RS232 signals
[R10]
5.2.2.2.3 Connecting to opto-isolated inputs (GPIO_OPTO)
These 4 inputs (OPTO IP1+, OPTO IP1-, OPTO IP2+, OPTO IP2-, OPTO IP3+, OPTO IP3-,
OPTO IP4+, OPTO IP4-) are current activated and require a current to flow from IP+ to IP-.
For a volt free signal (such as a simple switch), this is achieved by either:
a) wiring the switch between vehicle VBAT+ and OPTO IP+ and grounding OPTO IP-, or
b) connecting vehicle VBAT+ to OPTO IP+ and wiring the switch between OPTO IP- and
ground.
For signals that assert a voltage, connect the signal to OPTO IP+ and ground OPTO IP-.
They require a minimum of 8 V across + and – terminals to operate, and will tolerate applied
voltages of 32 V. These inputs draw 5 mA when 32 V is applied.
5.2.2.2.4 General purpose input (GPIO_IP)
These inputs can be driven 0 V to 32 V, or may be simply switched (pulled down) to 0 V. The
switching threshold is 0.3 V.
5.2.2.2.5 General purpose input (GPIO_IP4T)
This input is also capable of pulse counting.
5.2.2.2.6 General purpose output (GPIO_OP)
This is a short-circuit protected and current limited output capable of sinking 200 mA.
5.2.2.2.7 Relay output (RELAY)
This is a volt free relay rated at 2A at 30V.

5.2.2.3 Video outputs
Figure 9 - ASL360-SVS ECU Video outputs and Ethernet
The ASL360-SVS ECU generates one video output, but can provide this via 3 video output
connectors:
VGA (15 way D-type socket)
2 composite channels (single M12 socket)
The composite channels may be set to PAL or NTSC format. Not all output permutations are
supported; please refer to Table 6 below.

Table 6 - ASL360-SVS ECU video output permutations
* It is possible for composite video output 2 to be blanked by the ECU whilst maintaining video
output on composite Video output 1. (This feature could allow a screen connected to Video
output 2 to be blanked, while still outputting video to a DVR connected to Video output 1.)
+
Note that ASL360 CM2 cameras are PAL format, and therefore choosing NTSC will cause a
mismatch of input and output frame rates; PAL is the preferred option.
Refer to section 22.3 for how to make cables to mate with the VGA and composite video
outputs.
5.2.2.3.1 Short circuit protection
VGA signals do not have the benefit of short circuit protection. [R10]
5.2.2.4 Ethernet
Refer to section 22.4 for how to make cables to mate with the ECU’s Ethernet connector.
